The symbols are defined as follows:
Ze - charge number of the emitters,
Zp1, Zp2 - charge numbers of the ions,
Ne - concentration of the electrons,
Np1, Np2- concentrations of the ions,
Te - temperature of the electrons,
Ti - temperature of the ions,
C = Np2/(Np1 + Np2),
RT= Te/Ti,
b = F/F0, the electric microfield in the reduced scale,
F0 = e0/R02, so-called the normal field,
R0 - results from the relation (4/15)(2p)3/2R03Ne=1
D = (kT/4pe0Ne)1/2, the electronic Debye radius,
r = R0/D, the screening parameter.

The numerical calculation of the function Wr(b) have been performed for following values of the screening parameters r: 0.0, 0.2, 0.4, 0.6, 0.8
